Provision of fresh drinking water – Atmospheric water generators - KBCN1674

Atmospheric water generators can be used as an alternative to point-of-use water coolers connected to the mains water supply and drainage where it can be demonstrated that the water provision:

• Is potable (safe to drink) and can provide chilled and ambient temperature water.
• Would be able to meet the water consumption needs of the occupants.
• Be reliable in the local climatic conditions.

In this situation the water supply does not need to be connected to the mains water supply and drainage. Suitable access provision in areas must still be demonstrated.
